100 CONTRIBUTIONS TO THE FLORA OF NORTH CORNWALL. 
from potato-fields near Torpoint in Journ. Bot., N.S. vol. i., p. 265, 
and specimens of which I have since forwarded ‘to the Bot. ie! Club 
for distribution. In the article referred to I spoke of it as something 
different from the truly annual form of Watson’s B. campestris (ap- 
pearing in his Supp. Comp. Cyb. Brit., p. 22, as the second entry under 
No. 114. “ B. saeco ti Eng. Bot. No. 2234. An annual plant in 
turnip-fields ; Archer Briggs !’’), but cultivation of it has since shown 
me that it is identical with this other, and Ihavenow young plants, pro- 
duced from seed sown a few months ago, with the decidedly grass-green 
root leaves of it. When I collected the Torpoint examples last summer, 
but few, and those small, specimens had escaped the labourer’s hoe ou 
of the lines of potatoes, and on them alone were all the leaves perfect ; 
but they had run up so quickly into flower that the grass-green rosette 
was absent, and hence arose my mistake in supposing them to be a 
new form fe the larger plants the lower leaves had rotted away, 
partly earth having been drawn up around their stems as well 
as about Dises of the. atop The only forms growing about Plymouth

truly ual Brassica and the plant given by Watson immediately 
after it in his Supp Comp. Cyb. Brit. as ‘1 campestris ?, or 
‘ Rapa sylvestris,’ a biennial plentiful along the Thames.”’. I suppose 
the Bude B. —_— to be one of these two ; but what is the Norcot 
Mouth B. Napus ? 
Viola odorata, L. Poughill. I have seen this in Cornwall only 
where the suspicion of its having escaped from cultivation attaches to 
it, — it is clearly indigenous on some of the limestone beds to 
the east of Plymouth, as mp a few miles from the eastern mane ine 
Rhamnus catharticus, L. Lansells. A very interesting addition to 
the county list, though I must confess the possibility of Dr. Hind’s 
having inadvertently written ‘‘ catharticus”’ for Frangula occurs to me, 
from the ae: of the latter shrub not being named at all by him, 
though so common in many om arts of Devon and Corn vail 
Rpilobium angustifolium, L. Boscastle. Is this «. macrocarpum, 
5 - or 8. brachycarpum, Leight, ? I have never seen either in 
any part of Corsa} though the first occurs as a doubtful native in 
one spot near feo ind the latter in another, where it is mani- 
festly only an ‘‘e rom an adjoining garden and shrubbe
